BK20104L220-T

Overview

The BK20104L220-T is a surface-mount ferrite bead manufactured by Taiyo Yuden, designed for high-frequency noise suppression in electronic circuits. It features a compact 0805 (2010 metric) package size, suitable for space-constrained PCB layouts. The component exhibits a nominal impedance of 22 ohms at 100 MHz, providing effective attenuation for electromagnetic interference signals within this frequency range. Its DC resistance is typically low, ensuring minimal impact on the power or signal line's direct current performance while maintaining structural integrity under standard operating conditions.

Feature Summary

• Provides targeted attenuation of high-frequency noise signals to enhance signal integrity
• Utilizes a compact surface-mount form factor for efficient board space utilization
• Constructed with stable ferrite material properties for consistent filtering performance

Applications

• Noise suppression in digital logic circuits
• Filtering in USB and high-speed data interfaces
• Power line decoupling in portable electronic devices

Procurement Notes

Verify the specific suffix 'T' corresponds to the required tape and reel packaging configuration as defined in the manufacturer's official documentation. Confirm that the impedance tolerance and DC resistance values align with the circuit design requirements before finalizing procurement orders to ensure compatibility with system specifications.

Selection Notes

Select this component when a 22-ohm impedance at 100 MHz is required for noise control in 0805-sized footprints. Evaluate the DC resistance characteristics to ensure they do not exceed allowable voltage drop limits in the target application. Consider the thermal rating and current handling capabilities relative to the operational environment to prevent performance degradation.

Part Context

This part belongs to Taiyo Yuden's BK series of ferrite beads, which are widely used for EMI suppression. The BK series offers various impedance levels and package sizes to address different filtering needs across consumer electronics, automotive systems, and industrial equipment. The 2010 package provides a balance between filtering effectiveness and physical footprint constraints.

Replacement Considerations

Consult official cross-reference lists from Taiyo Yuden or authorized distributors for verified equivalent parts. Ensure any substitute matches the 22-ohm impedance at 100 MHz and maintains compatible DC resistance and current ratings. Verify package dimensions and terminal configurations to guarantee mechanical fit without redesigning the PCB layout.
